    As other have mentioned you can't display an image in an alert. The solution is to show it on the webpage.

    If I have my webpage paused in the debugger and I already have an image loaded, I can display it. There is no need to use jQuery; with this native 14 lines of Javascript it will work from code or the debugger command line:

    function show(img){
 var _=document.getElementById('_'); 
 if(!_){_=document.createElement('canvas');document.body.appendChild(_);}
 _.id='_';
 _.style.top=0;
 _.style.left=0;
 _.width=img.width;
 _.height=img.height;
 _.style.zIndex=9999; 
 _.style.position='absolute';
 _.getContext('2d').drawImage(img,0,0);
}

    Usage:

    show( myimage );

    Use jQuery dialog to show image, try this code

    <html>
  <head>
    </head>
    <body>
     <div id="divid">
         <img>
     </div>
    <body>
  </html>


<script>
 $(document).ready(function(){
      $("btn").click(function(){
      $("divid").dialog();
   });
  });  
 </script>

    `

    first you have to include jQuery UI at your Page.

    Short answer: You can't.

    Long answer: You could use a modal to display a popup with the image you need.

    You can refer to this as an example to a modal.

    Alert boxes in JavaScript can only display pure text. You could use a JavaScript library like jQuery to display a modal instead?

    This might be useful: http://jqueryui.com/dialog/

    You can do it like this:

    <!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
  <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
  <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
  <script>
  body {
    font-family: "Trebuchet MS", "Helvetica", "Arial",  "Verdana", "sans-serif";
    font-size: 62.5%;
}

  </script>
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

<div id="dialog" title="Basic dialog">
  <p>Image:</p>
  <img src="http://placehold.it/50x50" alt="Placeholder Image" />

</div>


</body>
</html>
